A self-described "sailor on horseback," London loved adventure on land and sea. For a water-borne adventure in his native Oakland, embark on an eye-opening urban kayak expedition with the help of the folks at California Canoe and Kayak, appropriately located on Jack London Square. You'll launch right from the marina, paddle past ritzy yachts, then slide into the cool, calm waters of the Oakland Estuary. From the dock, beginners should go left to explore Alameda's houseboat neighborhoods, circumnavigate Coast Guard Island, and check out the mix of weathered warehouses and chic new condos on Oakland's waterfront. More experienced paddlers can go right, skimming past titanic tankers and colossal cranes into the wide-open waters of the Bay. Soak up stellar views of San Francisco's downtown and stop at the picnic-worthy beach about an hour into your paddle. For a nighttime perspective, catch this Saturday's full-moon tour ($49).

BONUS: Kitty-corner to California Canoe and Kayak, London's favorite watering hole, the intimate Heinold's First and Last Chance Saloon, has been pouring beer and booze since 1883. Be sure to ask the barkeep about the sign that reads "WYBMADIITY." Adjacent to the bar is London's Alaskan cabin—imported piece by piece!
